In the training manual, in accordance with the program of discipline "Fundamentals of tribology" , the Association of Tribologist Engineers of Russia , The main provisions of the contact interaction of solids , properties and topography of their surfaces , Nature and types of external friction , The influence of various factors on friction . Described various types of wear, the role of lubrication, temperature, friction and antifriction materials for mating parts, the main ways to increase the wear resistance of materials and machine parts. Calculated methods for assessing the wear intensity of the most common triboconjugations. The main provisions of modeling of tribological processes, methods of testing for friction and wear, as well as the role of tribology in solving socio-economic problems caused by tribological sources are considered. losses from underproduction, loss of all types of resources, deterioration of environmental friendliness, energy efficiency of various modes of transport, etc. The manual is designed for students of technical specialties studying this discipline or its sections in other disciplines, graduate students, scientific and engineering specialists in the field of friction, wear and lubrication in machines . ; Grif: Recommended by the Educational and Methodological Association for Education in Food Technology and Food Engineering as a teaching aid for students of higher educational institutions , students in specialty 170600 "Machines and apparatuses of food production" direction of training of the certified specialist 655800 "Food Engineering" .
